From the shores of Lake Superior, tucked away in the great North Woods, “Tent Show Radio” broadcasts the summer lineup of Big Top Chautauqua’s finest acts. Now, celebrating their 20th anniversary on public radio, the crew is taking the show on the road. New York Times best-selling author, host and humorist Michael Perry and the Blue Canvas Orchestra are setting up camp at the Fox Cities P.A.C. on their first-ever tour, bringing the best of “rural life” to the “big city.”
